Coding Terms You Need to Know in 2023
Coding is an important part of the world today, and almost everything we do involves computers. While it isn’t important for everyone to know coding terms, anyone who wants to learn to code can benefit from learning more terminology. For example, according to PayScale, people with programming certificates earn an average salary of $72,000.
Tech beginners must get comfortable with basic terms along their coding journey. While you may never have to learn how to write out procedural code or a code base from scratch, there are plenty of terms that can be useful to understand. The guide below introduces you to coding terms that you must familiarize yourself with programming and coding.
What Is Coding?
Coding is the designing of instructions in a language that computer systems understand. This helps a computer carry out whatever task a human wants it to do. Professionals can design software and construct computers in web development, software development, and mobile app development. Coding is just a way that humans can communicate with computers.
How Do I Start a Coding Career?
To start a coding career, you need to get an education, build your portfolio and professional network, apply for entry-level jobs, and earn certifications. You don’t have to follow the steps in order, but you must get educated on the specific field you are interested in. For example, you should know medical coding vocabulary and key terms if you want to enter the medical field.
How to Learn to Code in 2023
First, to learn to code, you have to choose the educational path that best suits your career goals. You can go to college for a Bachelor’s Degree in Computer Science or Programming, join a coding bootcamp, or enroll in an online program. All of these options are great depending on your career path and desired choice of job.
The best coding bootcamps are designed specifically to help you learn to code and start a career in technology. They are short-term, immersive, and flexible, making them available to anyone with the drive and potential to learn. A coding bootcamp will help you gain in-demand skills and stand out in the job market.
Two added advantages of coding bootcamps are their hands-on approach and their career services that they provide during or after the program. The hands-on learning approach helps students to practice the skills they’ve learned and build their portfolios. The career services prepare them to secure jobs at the end of the program.
Online courses are short programs offered by online providers like Coursera and Udemy. They can help you learn the skills to either start a career or advance in your career. You can learn to code through any of the numerous online learning platforms available today. All you have to do is select the course that offers the skills you need in a method that suits you best.
The best thing about online programs is the fact that the lessons are usually pre-recorded videos that you can watch at any time. This means the learning is self-paced and can be completed based on your schedule. You also earn a certificate of completion at the end of some courses to help you boost your CV and prove your skills to potential employers.
These college and university programs will equip you with the general skills you need for a specific field. Unlike coding bootcamps and online training programs, they are not as hands-on. However, they are more in-depth and preferred by employers. To learn to code with degree programs, you will have to enroll in computer science, IT, or other related programs.
Before you apply for a program, you should check the admission criteria at your time of admission. Whether you want to get an associate degree, a bachelor’s degree, or even a master’s degree, you will need to commit to your semester credit hours and put in the work. Degree programs are much longer than bootcamps, but they are worth it.
Free Coding Resources
There are hundreds of coding resources available online that you can use to your advantage. These resources are excellent for those who cannot dedicate the time to a coding bootcamp, degree, or online program. You can utilize any of these resources by reading and practicing what you learn in real life.
